Entering Battery, PV & Inverter price into the True Zero Spreadsheet using $ values

To determine battery price to enter this table can be used:

https://www.solarchoice.net.au/solar-batteries/price/#Average_installed_solar_battery_prices_February_2026

Instructions:

1. Choose the Battery Only Average Installed price
2. Minus 30% to remove the labour component
3. Use this figure to enter into the True Zero Spreadsheet in the electrical tab.

Eg.  

1. 10kW battery from the table below = $8650
2. Minum 30% ($8650x30%=$2595).  $8650-$2595=$6055
3. $6055 goes into the True Zero Spreadsheet

The same method can be used for entering PV system values.  Go to the link below and use the table in the same way, less 30%.

Instructions:

1. Choose  a PV system size from the "All" row.
2. Minus 30% to remove the labour component.
    This will be the combined price of the PV & Inverter system.
3. To work out the individual cost of the PV panels and the Inverter, divide this price so that 3/4 goes to the PV and 1/4 is for the Inverter.
4. Use these figures to enter into the True Zero Spreadsheet in their respective cells in the electrical tab.

Eg.  

1. 10kW panel PV system from the table above = $9550
2. Minus 30% ($9550x30%=$2865).  $9550-$2865=$6685
3. Work out the split for panels and inverter
   For PV panels $6685x0.75=$5013.75
    For inverter $6685x0.25=$1671.25
4. $5013.75 goes into the True Zero Spreadsheet in the "$ PV Panels & Rack" cell
    $1671.25 goes into the True Zero Spreadsheet in the "$ Inverter" cell

And for those that need prices for bigger sizes beyond 10kW, here's some average prices extrapolated from the table above:

You can of course do the same process using prices or quotes you get from suppliers in the market if choosing a specific product.
